Old TVs are still an option for consumers who
aren’t ready to pay for a new device for their needs. Television technology is
developing very strongly, which means that with just a little basic knowledge
and understanding when choosing, consumers can choose to buy used products. .
Here are a few notes when choosing to buy second-hand TVs.
1. Determine the demand for use
New TVs usually have a warranty period of 2
to 3 years depending on the manufacturer and the different types. It is best to
look for TVs that are still under warranty. Consider before you buy an old TV
– The price can pay is how much?
– Technology wants to experience?
– Where is the television set in the living
– How long will it last?
– Where do you buy it?
2. Identify the brand
Choosing reputable and famous brands will be
very helpful in buying an old television. Reputable brands usually have higher
quality warranties and support, and sometimes even with products that are out
of warranty. In this case, customers will have to pay an additional fee to
receive genuine service, which is also relatively worthy and assured. The
determination of the trademark used also provides useful information about the
device such as model, product model, applicable technologies, warranty period,
and its policies.
3. Check on equipment appearance
Whether buying new or used products,
consumers always need to carefully check the appearance of equipment. See if
the old TV is distorted where the screen is, whether the screen has been
scratched or broken, whether the stand parts, cases, and associated parts have any
problems. Next is to check the screen surface is not scratched, yellowing. And
if you’re technically proficient, see if there’s any electrical leakage. In
addition, if the old TV shows signs of refreshing, it must be checked more
closely because it has certainly been replaced with the original, non-original
parts – resulting in the manufacturer’s refusal of warranty. when needed.
4. Check the picture light of the TV
With current types of TVs, broken screen lights are very common, one of the most common errors of LCD TVs. The cost of replacing a burned-out light bulb is very expensive, costing about 40-50% of the value of the television. This is the most important and valuable component of a television. Check the picture light by turning on the TV to see if it is up quickly. If turned on, the sound is already there and wait for about 5, 10 seconds for the new image to appear, sometimes slightly blurred, after a while, the definition will mean the tail of the TV is old, should not be bought. To try out the picture light, turn the TV on and off repeatedly. While the TV is active, put it in Mute mode and then put your ear to the TV casing to hear if there is an abnormal noise coming from behind the TV. If so, it is likely that the video light is broken.
5. Check the picture, sound and the ports connected
When checking the image quality of an old TV,
pay attention to the following: the truthfulness of the color, brightness and
viewing angle (which reflects the image quality of an LCD TV when changing the
viewing angle from side to side view). According to the LCD manufacturing
industry standard, it is still acceptable under 5 dead points. The color
gradation of the television must be uniform.
Check the sound of the old TV with the test
videos available in the machine, try to increase or decrease the volume of the
TV suddenly to see if the sound is cracked or broken.
The connectors are usually located on the
back or side of the screen. Depending on the type of TV, there will be
different ports (HDMI, USB, antenna), even you should check the headphone jack,
to avoid damage.
6. Check keys, remote control
These are the most basic control parts of a
television and also need to be checked before making a purchase. Try pressing
the keys found on the TV, usually the keys or touch keys. For remote controls,
ask the old owner to install a new battery to check if the buttons and controls
of the remote control are working properly.
